Medications for neuromyelitis optica spectrum disorder (NMOSD) are used to treat this condition and reduce the risk of relapses. They work by targeting the immune system to reduce inflammation and prevent attacks on the nervous system. Common classes include monoclonal antibodies complement inhibitors. Monoclonal antibodies like Enspryng (satralizumab) and Uplizna (inebilizumab)are usually given as injections. Complement inhibitors, such as Ultomiris (ravulizumab), are also injections. These treatments offer different ways to help manage NMOSD and improve your quality of life.
